Rendering on cob

[dllive]

Hi guys,

I have a 200 year old house. The render has blown around a window frame. I was told by a neighbour that Ill need to make up a lime/cement mix for the render (and then use a tyrolean gun to match it to the original wall). The wall is nearly all cob.

Does anyone on here have experience of rendering a cob wall? What sort of mix should I use? Is using a tyrolean gun easy and should I just use a cement mix in there?

Thanks

If you need any more advice PM me. One thing you should take into consideration is the weather, you need good weather unless you can cover the job.

Don't mix lime render in a cement mixer, it collects into clay like balls, best to hand mix or use a paddle mixer.
